Аннотация: In regions with negative average daily temperatures, the development of the construction sector, including transport infrastructure facilities, requires increasing the efficiency of heating systems and deicing systems, while reducing the material consumption of their production. In the study, samples with dimensions of 70x70x70 mm and products with dimensions of 500 × 500 × 50 mm were made from electrically conductive coarse aggregate concrete. Additives of industrial soot suspension - 7% and carbon fiber - 1% were used as modifiers. The additives were introduced individually and in combination. The developed compositions ensure the mechanical compressive strength of concrete on the 28th day of more than 40 MPa. The combined use of modifiers allows the surface of the product to be heated from 21°C to 34°C within 30 minutes. Physicochemical studies of the compositions conducted after 3 cycles of heating and cooling showed optimal homogenization of carbon-containing materials and the absence of chemical interaction between carbon fiber and components of the mineral matrix. The obtained indicators of electrical and mechanical properties prove that it is possible to manufacture products based on the optimal composition that provide repeated heating and are optimal for use in the improvement of urban areas.
